These grease seals have the purpose to seal the connection between support arms and front axle on vw T1 -67, so that lubricating grease remains in the front axle and sand and moisture cannot penetrate into the front axle housing. 

The latter has rather destructive consequences on the front axle bearing and support arm running surfaces, so cracked, hardened ones should be replaced immediately. 

We deliver these rubber seals per 4 pieces.
